MIKE "THE SITUATION" SORRENTINO
Cause: Spay/Neuter advocacy
How He Got Involved: Who would have guessed that "Jersey Shore" bad boy Mike "The Situation" Sorrentino cared about safe sex? Well, when it comes to companion pets, he does! In October, the MTV star signed on to be a PETA spokesperson, hoping to raise awareness about neutering and spaying cats. "When I hear something on the news about animals being abused, it's a very, very sad thing because animals don't have a voice," he said in a PSA. It may be a little risqué, but sometimes that's what it takes to instill the message.
